Construction work will begin this morning on a €50m conference venue in west Dublin which will be eight times the size of the Government's proposed National Conference Centre. Property developer Jim Mansfield's project, to be called the National Convention Centre of Ireland, will hold up to 16,000 delegates with most of the work expected to be completed by next March. Mr Mansfield intends to invest around €800m in the convention centre, a new hotel, a heritage-style village, the redevelopment of the Weston airport, which he also owns, and golf courses. He also plans funding an extension to the Luas line to Citywest which could cost up to €20m.
